One object of this invention is to provide looking mechanism for depressible keys,

which is under the control of said keys.

Another object is to control the unlocking of the keys a manipulative lever on certain Operations. p

WVith these and incidental objects in View, the invention consists of certain. novel teatures of Construction and combinations of parts, the essential elements of which are set forth in appended claims and a preterred form or embodiment of which is hereinafter described with` reference to the drawings which accompany and form part of this specification.

F ig. 6 is an elevation of the right hand end of the machine showing the Operating mechanism and a part of the releasin' mechanism.

The above cited applications disclose a machine provided with a plurality of banks of amount zeys with each of which. is associated a difierential mechanism for the purpose of adjust-ing indicators, type carriers shown in the drawings which form a part ot" this application.

The machine to which this invention is shown applied, is well adapted I'or use in business places where itis desired to register a plurality of items and then issue a receipt upon which is printed the amount of each item together with the total .thereot.

The keyboard of the present machine is substantially the same as that disclosed in the above cited applications and as this invention is more particularly directed to the transaction keys, a description thereot will be given forthwith.

Transaction keys The transaction keys comprise two groups arranged in a single bank and mounted in a common frame (Fig. 1) supported by rods 3% extending between the side plates of the machine. The upper group of keys is used in registering multiple item transactions, and the lower group of keys 31 is used in registering single item transactions.

The keys are held in .their normal positions by the usual springs (not shown) and are retained in .their ,depressed positions by a spring-actuated looking detent bar 35 engaging pins 36 on the keys.

The detent bar 35 is pivotallymounted on links 37 and 38, which swing on pins carried by the key rame 33.

The key pins 36 also wipe against 'the beveled walls of recesses formed on a movable releasing bar 39, to shift the bar and operate interlocking meehansm between the transac-' tion keys and a starting key har 105, Fig. 6. The releasing bar 3 is pivotally supported by links 40 and 41 (Figs. 3 and 4) also pivoted onthe key fraine 33.

A release key 32 is located on the key treme between the groups of multiple and single item keys and 31, respectively. The release key 32 is equipped with a pin 36 to shitt the detent bar 35, and release an accidentally depressed transaction key in either group, as illustrated ii Fig. 1.

Any of the single item keys 31, when d d, Contacts its key pin 36 against the inc i e i ning hook on the detent er to Shift the har and hook the tension of a usual restoring spring 3:31 so ai the pin 36 below the bill of the hee-k, the spring 351 will return +1 y.

the path of the Associated with the transaction keys is a dilierential mechanism provided for the purpose of selecting totalizers, usting indicators (not shown) and printing mechanism (not shown). This ditlerential mechanism also co-operates with the transaction key locking mechanism, as will he hereinatter dvscrihed,

Te drive the difierential mechanism a drive shaft 42 is provided with a pair of cams 43 pinned thereto and `oo-operating with roll 44, carried hy a Y-shaped lever 45. This lever is pivoted on the difierential hanger 46 and at its upper end is connected to a sesment a by means of the link 43. The shart 42 receives a complete clockwise rotation on each cycle of operation of the machine, which through the mechanism just described, rocks the segment 47 first clockwise and then counter-clockwise to its normal position. A differentially mova le arm 49 carries a latch 50 supported thereon a hell crank 51 and an arm 52 The latch 50 normally connects the arm 49 to the segment 47. As the segment 4? moves clcckwise, the dii'ierentially movable arm 49 is curried with it until an arin 53, of the bell crank l., strikes the end of the depressed key, whereupon the bell crank is rocked ceunter-clockwise to disengage the latch 50 from the segment 4?. As the latch thns iisengaged, a nose 54 thereon moves into engagement with a notch 55 in a har 56 supported at its upper end by the hanger 46 and at its lower end hy a rod 5?. 47 returns to its normal position the oifierentially movable arm 49 is again connected thereto and is returned to its normal position.

/Vhen entering a multiple item transaction, the operated transaction key 30 should' be locked in depressed position, and all other transaction keys locked against depression until the compietion ot the entire trensaction. This result may be Conveniently ohtained arranging the inclined walls of those recesses in he releasir har 39 which liein the paths of the multiple item keys 30, so that upon depression ot a key 30, the releasing ber 39 is given a greater extent of movement then is inparted to itby the single item 31, and by providing the link 41, to Which d of the releasing har 39 is pivi e notch 65 4) engageable hy iournaled on a shutt 61. single item key 31 is depressed, her 39 is not shifted a suiicient ance to Swing the notched link 41 far enough to bring the 'notch 65 into the path ot the looking bail 64.' But, owin to the longer incline of the Walls of the releasing her 39, beneath the multiple item keys 30, depression of a multiple item key Will Shift the releasing bar 39 and its link 41 to such an extent, that upon complete depression of the key, and the restoring of the detent har 35, and its link 38 to looking position, the notch 65 in the link 41 is in the path of the looking hail 64, prepsratory to the entry of the edge ot the looking beil 64 thereinto An arm 60 pivoted on the release shalt 61 fast with thelocking hail 64 to control the letter. The inner free end ot the bail arm 60 extends inwardly into the path of a stud 63 projecting from the difierentially movable arni 49, which stud maintains the bail arm 60 and the looking bail 64 in idle position against the tension or" a spring 62 connected With the arin 60 which tends to rock the arm 60 and looking bail 64 counter-clockWise (Fig. 3) towards the li k 41.

Depression oI" sn item key, and amount keys, followed hy en operation of the machine, rocks the diterential arm 49 clockwise as previously described, to select the proper totalizer, and in so doingthe differential arin 49 releases the bail carrying arin 60 to the action of the spring 62, which rocks the arm 60 and its lockin g hall 64 counter-clockwise.

The hail then enters the notch 65 to hold the depressed multiple item key 30 in its depressed position throughout two or more Operations of the machine.

The estended travel permitted the looking hail. 64 when it enter-s the notch 65 in the link 41, positions the hall beneath the link 38 and As the segment' thereby looks all the other keys in the item bank against depression.

*When a single item key 31 is depressed, and the machine is operated, the limited travel permitted the looking bail 64 is such that the free end of the hail arm remains in the path of the stud 63 when the bail contacts the nnnotched end of the link 41, so that upon the return of the dil'lerential arm 49 at the end of the operation, the stad 63 contacts the hail arm 60 and restores it together with the bail 64, to idle position. But when a multiple item key 30 is depressed and the machine operated, the extended travel of the hail 64 withdraws the free end of the arm 60 from the path of the stud 63 on the differental arm 49.

T herefore, to eilfect the release of the multiple item keys 30, and the restoring of the locking` bail 64 to its idle position, a total lever (Fig. 5) of the usual type, and having` the usual cam slot 74, is provided. After all the items of a multiple item transaction have been entered in the machine, the totai lever 70 is manually shifted from its normal add position to the item total position, and after the total is printed, the total lever is restored to its normal add position.

A roiler 73 carried on one arm of a lever 71, pivoted at 72 enters the cam slot 74, the opposite arm 'i' 6 of the leverhaving 'orined on one edge thereot a cam recess 761. A link 75 also pivoted at 72 and overlying the arm 76 of the lever 71 has a complementar" cam recess 78 formed on its edge, which cooperates with the cam recess 761 formed in the arm 76 of the lever '71 to constitute a cam slot. A spring' ?7 connects a stnd 751 on the link 75 with the arm 76 of the lever 71 to hold these parts together with the stud 751 in contact with the upper end of the arm 76. This arrangement provides a fieible cam mechanism which will yield to prevent ir.- jury to the machine in case the sha'ft 61 is locked hy a depressed key, at the time the total lGVGY 70 is shil ted from its add position. A crank 80 fast on the shai t 61, on which the hail carrying arm 64 is pivoted, carries a roller 1 9 entered in the cam slot tormed hy the complementary cam edges 761 and 78 ot the arm 7 6 of the lever 71 ane he link75.

When the total leVer 70 is adjusted f om its add position to its item total position, its cam slot 'Z 4 rocks the lever 71 in connte.,

tion of the main drive shaft 42 of the machine, during the latter part of the first of which cycles the shaft 61 is rotated slightly fai-ther in a clockwise direction by means to he hereinafter described, which presses the tappet 81 against the stnd 82 to rock the hail arm 60 clockwise sufciently to return the 'free end of the bail arm into the path ot the stud 623 on the diilerentially movahle arm 49 while the latter is at a point some distance above the hail-arm 60, so that as the differential arm 49 is restored, its stnd 63 strihes the free end of the hail arm 60 and withdraws the locling hail 64 'from the notch 65 in the link 41 to permit the release of the depressed multipie item hey 30.

Mechanism will now be described for giving the shaft 61 its second movement, mentiened above.

A lever (Fig. 6) pivoted at 91 and is coimected at its npper end by link 92 to an arm 93. ,ied to the shaft 61. At its 90 is connected to a pitlower end ti, 7 er man 941- giided hy a stnd 95 monnted in the right hand 'treme oi"? the machine. The pitma 94 carres a rol' i' 96, adapted to co-operat with gi o-ve in a cam 97, free on the stad 95. The roller 96 is normally in po sition withdrawn from the groove and in a notch forme-d therein. It will he recalled when the total lever 70 is moved to prepare the machine for a total taking operation the sha'ft 61 is rocked slightly clockwise. This movement th ough the mechanism just described will di, i age the roller 96 from the notch and move it into cooperative relation with the groove 97. At the same time a slide 98 is moved under the influence of the pitman 94 in a well known manner, to lock the cam 97 to a gear 99, free on the stud 95, so that the cam will be rotated with the gear upon operation of the, machine in a manner herenafter to be described. The gear 99 and the cam 97 receive one counter-clocltwise rotation on each total taking operation of the machine. Near the end of the first cycle of operation of the shaft 42, the pit-man 94 will be moved te the left by the cam 97 and will rock the shaft 61 cloekwise to move the bail 64 ont of the notch 65, as described above.

Machine Operating and relcasi g mechcmsm The machine is operated manually by means of a crank 100 (Fig. 6) or hy an electric motor (not shown). The crank 100 has secured thereto a gear 101 which meshes with gear 99. Pinned to the drive shaft 42 is a gear 102 also meshing with the gear 99. Two clockwise rotations of the crank 100 and gear 101 impart one-half of one countercloclrwise rotation to the gear 99 which in turn gives the gear 102 and the shaft 42 one clochwise rotation on each adding operation of the machine.

The elect'ic motor is not shown or deto a downwardly extending arm of scrbed heroin as it is old and well known in the art and has no part in the' present invention.

The machine is released for operation pressing a clerk s key (not shown), the transaction hey 30 or 31 (Fier 1) and starting bar 105 (Fig 6). This permits a release shait 106 to be rocked clocl wise to release the machine *for operation in a manner 'nlly shown and descrihedin the above cited .ap-- plications. The shatt 106 normally tends to rock clockwise nn der the influence of a spring 107 compressed oetween the bottom of a slot 103 in a lin 109 and the shonloers of two g. idcntical spring pilot arms 110 monnted on the bifnrcated portion ot' :in arm which in turn is connected y means of a link 110 e bell crank 114, rock t e hell cranl: clockxise to remove lt from the pin 112, wherenpon the spring 107 will rock the shaf" 106 clockwise and release the machine fer operation.

An interlocl between the starting and transaction key is provided Whereby'it is necessary to press a transaction key 30 or 31 before the machine can he released by 'n'essing the starting bar 105. Pinned to the shaft 106 is an arm 120 (Fig. 2) which carres a iattened stud 121 normally contacting a projection on an arm 122, pivoted on the shaft 123. The arm 122 is held in contact with a yoke 1241 by means of a spring 125. The yohe 124 has an npwardly extendarm 126 Contacting a pin 127 carried by the link 40, upon which is swnng the npper end of the releasing bar 39. Referring to Fig. 2 it is clear that, when, upon depression of a transacton key 30 or 31, the releasing bar 39 moves to the left, the yole 12 1 and the arm 122 will be roclred connter-cloehwise to remove the projection thereon from the path of the stud 121 thns leaving the shalt 106 free to he released upon depression of the starting' bar 105.

The shalt 106 is restored'to its normal position h means of an .arni 131 (Fig. pivoted at 91. This arm carries a roller 132 adapted to co-operate with a cam groove cut in the side of the gear 09 to give the arm 131 a regular excnrsion down. then hack to its normal position. The arm' 131 ca'rries a pin 13 1 normally engaging a notch in an opening' 137' in the link 109. Near the of an adding operation and near the end of total taking operation, as the arm 131 is given its excursion, it moves the link 109 down and rocks the shaft 106 connter-clochwise to permit the arm of the bell crank 114 to resume ne lower end oi" the lini; 100 to co-operate stnd 136 carried near the right hand end of 'the pith-lan 041.

moved the leit cam 07, de-

ibed

ci above, the link 100 is swung to the leit, which positions the lower end of the opening 13? therein in the path of the pin 13% so that on its downward movement the pin is ineiective to rock the shaft 106. These parte are restored to their co-operative relationship just before the arm 131 receives its second downward movement in total taking perations. This second movement of the '111 131 will on total taking Operations rock e thaft 106 to release the depressed transd restere the parte associated ng hey and transaction keys to noriiml positions. The machine is provided with a plurality totaliz rs monnted on three frames, 1 10, 1). Thetotalizer frames slid iaterally in the machine, s 1 13, to select the transaction and ation totalizers mounted thereon. pper totalizer treme 1 12 carries a grand which is not under control of the trannetion keys.

o select the transaction totalizer, the following mechanism is provided: y

Associated with the transaction difierential mechanism is a beam 144 (Fig. 1) pivoted on tl e arm 19 and bifnrcated to (zo-opvith pin in a link 145. A roller 139 is monnted on the Y-shaped lever 15 for the purpose oi' bringing the upper convex section of the heam 1 1 1 into a constant position against ahnb on the differential arm 19. The link 1425 is connected at its lower end to an .arm 1 16 secured to one end of a tube sur ronnding the shat't 1 17. Secured to the arm 146 is a segment gear 1 18 meshing with a racl 1 19, Secured to a Jar 150 slidably monnted on studs 151. The bar 150 has bent-over fianges 152 in which are shaped cam slots cooperating with rollers (not shown) carried by slides 153. These slides co-operate with projections on the totalizer 'frames-1:10 and 1 1-1, to slide them laterally in the machine, and select the totalizers to be used, all of which is shown and ,described in the above mentioned parent application. i While the forms of mechanisms heroin shown and described are admirably adaptod to fulfill the objects primarily stated, it is to be nnderstood that it is not intended to confine the invention to the forms or embodi ment herein disclosed, for it is susceptible of emhodiment in various 'forms all coming within the scope of the claims which follow,
